Technical and economic examining of replacement ACSS high capacity conductors rather than ASCR conductors in 20kV overhead networks

Today, due to increasing energy demand, the development of urban construction is obvious. On the one hand, due to the heavy demand of consumers and increase production capacity, they need to increase their intake Demand. The growths in urban areas, electricity distribution companies are forced to increase the installed capacity to posts and distribution lines. Therefore, to increase the capacity of medium voltage overhead lines up to 20 kV voltage levels will be need to increase the conductor cross section. Most of the electricity distribution network in Iran is ASCR conductors. In order to increase the cross area, they need further mechanical calculations and changes based on end-of angles and equipment. This study compares the technical and economic capacity replacement ACSS conductors instead ASCR without changing the makeup line and just replace the conductor with higher capacity are paid. For this purpose, the MCAL software (Mechanical Calculations) made for the line mechanical calculations have been used

This paper studies the effects of time of use program (TOU), which is one of the demand response programs in distribution systems. The objective used in this paper is to increase transformer life time as much as possible. To assess this program, a 250KVA transformer is assumed. At first the life time of the transformer is calculated based on the transformer actual load curve, then the optimal load curve taken from TOU is used to calculate the life time

Examining the effect of changes in 20 kV lines configuration to

 

  remove the limits of approach

Being positioned in 20 KV line limits of approach is one of the main reason to not sign the supply contract for some residential or commercial consumers. Guilan province’s cities, especially Rasht has gabled roof houses with a slope, and its streets are without a sidewalk or sidewalks are narrow and have trees. In addition the high price of land caused population density in the rurals. Existence of 20 kV overhead lines for the past years in these areas and lack of public awareness of power lines limits of approach rules has resulted in not signing the supply contract with new consumers in these areas. To address this problem, power distribution companies have to make a change to 20 KV lines configuration, which results in operational problems. In this paper the different problems of limits of approach, exact measuring the limits of approach area and examining different ways to remove the limits of approach with practical examples and the change in lines configuration solution is presented. Finally some ideas are suggested to improve their performance.

 

Keywords: first degree limits of approach, second degree limits of approach, removing the limits of approach, 20 kV overhead line

 Abstract - During recent years, producing electricity by wind turbines has increased. Different forms of new turbines connected to the network and the passive network and the production of scattered power systems are used. Consequences of drought reduced production last year and Hydropower, leading to the power plants was increased again, was the most electricity distribution companies through different methods to pay load shedding. Electricity production by the wind turbines can be very useful in peak hours, but the Conversely on this topic may also apply, when the peak hours, electricity is not effective and economic. Considering that wind power plants in Iran and Binalood, Manjil areas like other countries is entrusted to the private sector, produce an effective economic talk of peak hours is considered important. Various methods of storage on the electricity there. Method to compress the air in wind power new and important subjects which will be used today. This article reviews the methods used are paid at the time of peak

Combined Heat and Power-CHP

Combined production of electricity and heat energy saving method in which electricity and heat are produced simultaneously. Simultaneous production of heat from heating can order regional District heating) or in the process industries can be used

The two most common CHP system configurations are:

Gas turbine or engine with heat recovery unit

Steam boiler with steam turbine

Gas Turbine or Engine With Heat Recovery Unit

 

 

Gas turbine or reciprocating engine CHP systems generate electricity by burning fuel (natural gas or biogas) to generate electricity and then use a heat recovery unit to capture heat from the combustion system's exhaust stream. This heat is converted into useful thermal energy, usually in the form of steam or hot water. Gas turbines/engines are ideally suited for large industrial or commercial CHP applications requiring ample amounts of electricity and heat.

Power System Capacitors ebook

Since transmitting reactive power over long distances is not feasible, power systems integrate power factor correction capacitors to provide local reactive power compensation. With a wide range of options available and with the tremendous changes that have occurred over the past few decades, a comprehensive, up-to-date book on power factor capacitors is long overdue. Power System Capacitors fills this void by providing the fundamentals, applications, protection issues, and system impacts for a broad spectrum of capacitor applications
